Givens:
- There are 5 tall glasses and 3 juice glasses.
represents the cost of each tall glass.
represents the cost of each juice glass.

Answer:
100.54m²
Step-by-step explanation:
Given parameters:
Volume of the cylinder = 288pi cubic meters = 288πm³
Height of the cylinder = 9m
Unknown parameter:
Area of the base = ?
Solution
To find the unknown which is the base area of the cylinder, we simply use the formula of the volume of a cylinder.
Volume of a cylinder = Base area x height = πr² x h
where π is a constant
r is the radius of the cylinder
h is the height of the cylinder
From here, we make area the subject of the formula:
Base area(πr²) =
Base area = = 32 π = 100.54m²
